Since there will be 28 people, and each of them will drink 3 glasses, you just multiply the number of people times the number of glasses they will drink each, so 28*3. The result is 84.

I hope this helped! :D

Find an equation for the nth term of the arithmetic sequence. -15, -6, 3, 12, ...

Mariulka [41]

Answer: $t_{n}=-15+9(n-1)$

Step-by-step explanation:

The formula for finding the nth term of an arithmetic sequence is given as:

$t_{n}=a+(n-1)d$

$a =$ first term = -15

$d =$ common difference = -6 - (-15) = 9

$n =$ number of terms

substituting into the formula , we have :

$t_{n} = -15+(n-1)9$

$t_{n}=-15+9(n-1)$

Help with math please???

Tresset [83]

Okay, let's see...

The problem is asking for a linear equation most likely in the form of y=mx+b

y is another way to say f(x)

m = slope

b = y intercept

Let's start with the y intercept first.

Y intercept means ' When does the line touch (intercept) the y axis.

In this case, if you look at the graph, the line touches the y axis at -1.

-1 will replaces b

To find the slope we are going to take 2 precise points from the graph.

Lets use (0,-1) and (-6,4)

To find the slope, we're going to use $\frac{(y_{2} -y_{1} )}{(x_{2} -x_{1} )}$

4 - (-1) / -6 - 0

Solve, our slope is 5/-6

That is our m

Our final equation is

$f(x)=\frac{-5}{6} x -1$
